 evidences of lunar influence on the weather quite as questionable as those 

 of discoverable planetary influence. 



My predictions of increasing range and regularity of disturbance, in 

 approaching the equator, had been confirmed by comparisons of observa- 

 tions in Great Britain, Canada, New England, Philadelphia, Lisbon and 

 San Francisco. Their apparent failure in an island which seemed, on 

 many accounts, so favorably situated for their verification, cast a shadow 

 of doubt on my previous conclusions, and I was even inclined to ask if it 

 could be possible that the many coincidences which I had taken as in- 

 dicative of law, were merely accidental. 



This skepticism, howevei", was soon removed. The cumulative action 

 of the aerial tidal-waves in blending different currents, of which I have 

 so often spoken, may be easily obscured, if it is not wholly overborne, by 

 insular influences, by the violent hurricanes to which the Windward 

 Islands are subject, and even by the occasional intrusion of the south- 

 easterly trade-winds. Where there is a liability to sudden heavy rains, 

 any one of which would suffice to make important changes in a curve
